Lip compositions

ABSTRACT

Lip compositions, in particular lip oil compositions, capable of forming a multilayer structure after application to lips are provided, as well as methods of applying such compositions to lips.

This application claims the benefit of priority under 35 U.S.C. §119(e) from U.S. Provisional Application Ser. No. 62/316,309, filed Mar. 31, 2016, the entire contents of which is hereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to lip compositions, in particular lip oil compositions, capable of forming a multilayer structure after application to lips. Such compositions allow for benefits associated with multilayer lip oil products without having to engage in a multi-step application process.

DISCUSSION OF THE BACKGROUND

Currently, lip oil compositions typically provide shine or gloss to lips, but without any effective amount of coloring. In contrast, current lip tint products typically provide coloring, but without effective shine. Further in contrast, current lip stain products typically do not provide effective shine and actually stain the lips. All of these current products are inferior for purposes of providing both shine and color to lips.

Thus, there remains a need for improved “single step” lip oil compositions having improved cosmetic properties, particularly good color, wear, feel, and/or shine (gloss) characteristics upon application without staining lips after application.

Accordingly, one aspect of the present invention is a care and/or makeup and/or treatment composition for lips which has good cosmetic properties such as, for example, color, feel, and/or gloss (or shine) upon application, and which can be applied to lips without having to engage in a multi-step application process and without staining the lips.

SUMMARY OF THE INVENTION

The present invention relates to lip compositions, in particular lip oil compositions, capable of forming a multilayer structure after application to lips.

The present invention also relates to lip compositions, in particular lip oil compositions, capable of forming a multilayer structure after application to lips, wherein the compositions comprise at least two immiscible components prior to application. Preferably, immiscibility of the immiscible components results from an incompatibility between the two components when the composition is at rest, incompatibility between the two components after application to lips, or both.

The present invention also relates to lip compositions, in particular lip oil compositions, in the form of an emulsion capable of forming a multilayer structure after application to lips, wherein the compositions comprise at least two immiscible components prior to application. The aqueous phase(s) of the emulsions may be present in one or more of the immiscible components. Preferably, immiscibility of the immiscible components results from an incompatibility between the two components when the composition is at rest, incompatibility between the two components after application to lips, or both.

The present invention also relates to anhydrous lip compositions, in particular lip oil compositions, capable of forming a multilayer structure after application to lips, wherein the compositions comprise at least two immiscible components prior to application.

The present invention also relates to lip compositions, in particular lip oil compositions, in the form of a dispersion capable of forming a multilayer structure after application to lips, wherein the compositions comprise at least two immiscible components prior to application. The dispersions may contain water, or the dispersion may be anhydrous. Preferably, immiscibility of the immiscible components results from an incompatibility between the two components when the composition is at rest, incompatibility between the two components after application to lips, or both.

The present invention also relates to colored lip compositions, in particular lip oil compositions, capable of forming a multilayer structure after application to lips, wherein the compositions comprise at least two immiscible components prior to application. The compositions further comprise at least one coloring agent which may be present in one or more of the immiscible components. Preferably, immiscibility of the immiscible components results from an incompatibility between the two components when the composition is at rest, incompatibility between the two components after application to lips, or both.

The present invention also relates to methods of treating, caring for and/or making up lips by applying compositions of the present invention to lips in an amount sufficient to treat, care for and/or make up lips.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the expression “at least one” means one or more and thus includes individual components as well as mixtures/combinations.

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about,” meaning within 10% to 15% of the indicated number.

“Film former” or “film forming agent” as used herein means a polymer or resin that leaves a film on the substrate to which it is applied.

“Polymer” as used herein means a compound which is made up of at least two monomers.

“Substituted” as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, hydroxyalkyl groups, and polysiloxane groups. The substituent(s) may be further substituted.

“Volatile”, as used herein, means having a flash point of less than about 100° C.

“Non-volatile”, as used herein, means having a flash point of greater than about 100° C.

“Anhydrous” means the compositions contain less than 1% water. Preferably, the compositions of the present invention contain less than 0.5% water, and most preferably no water.

“Transfer resistance” as used herein refers to the quality exhibited by compositions that are not readily removed by contact with another material, such as, for example, a glass, lips, skin or artificial skin, for example, when eating or drinking. Transfer resistance may be evaluated by any method known in the art for evaluating such. For example, transfer resistance of a composition may be evaluated by a “kiss” test. The “kiss” test may involve application of the composition to human keratin material such as lips followed by kissing another material, for example, a glass, lips, skin or artificial skin, against the lips after expiration of a certain amount of time following application, such as 15 minutes after application. The amount of composition transferred to the substrate may then be evaluated and compared. For example, a composition may be transfer resistant if a majority of the product is left on the wearer's lips. Further, the amount transferred may be compared with that transferred by other compositions, such as commercially available compositions. In a preferred embodiment of the present invention, little or no composition is transferred to the substrate from the lips.

“Gloss” in compositions as used herein refers to compositions having with an average gloss, measured at 60°, of greater than or equal to 35, for example 40, preferably 45, 55, 60 or 65 out of 100, including all ranges and subranges therebetween such as 35-65, 40-65, etc.

The term “average gloss” denotes the gloss as it can be measured using a gloss meter, for example by spreading a layer of the composition to be tested, between 50 μm and 500 μm in thickness, on a Leneta contrast card or BYK Opacity chart of reference Form 1A Penopac using an automatic spreader. The layer covers at least the white and/or black background of the card. The deposit is left to dry for 24 hours at a temperature of room temperature and then the gloss is measured at 60° on the white background using a Byk Gardner gloss meter of reference microTRI-GLOSS. This measurement (of between 0 and 100) is repeated at least three times, and the average gloss is the average of the at least three measurements carried out.

The composition of the present invention may be in any form, either liquid or non-liquid (semi-solid, soft solid, solid, etc.). For example, it may be a paste, a solid, a gel, or a cream. It may be an emulsion, such as an oil-in-water or water-in-oil emulsion, a multiple emulsion, such as an oil-in-water-in-oil emulsion or a water-in-oil-in-water emulsion, or a solid, rigid or supple gel. The composition of the invention may, for example, comprise an external or continuous fatty phase. The composition can also be a molded composition or cast as a stick or a dish.

The compositions and methods of the present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful in personal care.

Compositions Capable of Forming a Multilayer Structure

In accordance with the present invention lip compositions, in particular lip oil compositions, capable of forming a multilayer structure after application to lips are provided. Such compositions allow for benefits associated with multilayer lip products without having to engage in a multi-step application process.

In accordance with the present invention, the lip compositions, in particular lip oil compositions, of the present invention comprise at least two Components, hereinafter referred to as “Component A” and “Component B.”

Component A is the component of the compositions of the present invention which forms the layer of the multilayer structure which is closest to the lip after application of the composition to the lip. This layer of the multilayer structure is hereinafter referred to as “Layer A.” In accordance with preferred embodiments, Component A/Layer A has an affinity for the surface of the lip owing to the surface energy characteristics between the two.

Component B is the component of the compositions of the present invention which forms the layer of the multilayer structure which is farthest away from the lip after application of the composition to the lip. This layer of the multilayer structure is hereinafter referred to as “Layer B.” In accordance with preferred embodiments, Component B/Layer B has an affinity for the air interface.

In accordance with the present invention, all weight amounts and ratios set forth herein referring to Component A and Component B refer to amounts of active material (that is, non-volatile material) in these components. Similarly, all weight amounts and ratios set forth herein referring to Layer A and Layer B refer to amounts of active material as Layer A and Layer B are present after evaporation of volatile solvent.

Prior to application to a lip, Component A and Component B are immiscible in the compositions of the present invention. Preferably, immiscibility of the immiscible components results from an incompatibility between the two components when the composition is at rest, incompatibility between the two components after application to lips, or both.

Preferably, immiscibility of the immiscible components results from differences such as, for example, differences in viscosity, glass transition temperature, interfacial tension, solubility parameters, density, and/or chemical/structural incompatibility of the components, and/or differences induced by temperature and/or pressure.

For example, immiscibility of the immiscible components when the composition is at rest can result from, for example, chemical/structural incompatibility, differences in the interfacial tension between the components such as, for example, differences in the interfacial tension between the phases within mutually compatible solvent(s), differences in viscosity, differences in the glass transition temperatures of the polymers within each phase and/or differences induced by temperature and/or pressure.

For example, immiscibility of the immiscible components when the composition is being applied can result from, for example, chemical/structural incompatibility, differences in the interfacial tension between the components, differences in density of the components after solvent evaporation, and/or differences induced by temperature and/or pressure.

Immediately prior to application and/or during application to a lip, the composition of the present invention is mixed or blended such that Component A and Component B are temporarily miscible upon application of the composition of the present invention to a lip.

After the composition of the present invention has been applied to a lip, Component A separates from Component B. As the composition dries on the lip to which it has been applied, immiscible Component A and Component B form a multilayer structure comprising Layer A and Layer B, respectively, on the lip such as, for example:

LAYER B LAYER A LIP

According to preferred embodiments of the present invention, after compositions of the present invention have been applied to a lip, Component B results in Layer B which is level: that is, Layer B is planar such that it has refractive properties to impart shine or gloss to the composition. In accordance with these embodiments, Component B has self-leveling properties: it results in a level Layer B after application. The gloss or shine of such compositions can be enhanced, if desired, by addition of one or more shine or gloss enhancing agents having high refractive index properties. Alternatively, such compositions can be provided with matte properties by addition of one or more mattifying agents.

According to preferred embodiments of the present invention, after compositions of the present invention have been applied to a lip, Component B results in Layer B which is not-level: that is, Layer B is not planar such that it imparts matte properties to the composition. In accordance with these embodiments, Component B does not have self-leveling properties: it results in a non-level Layer B after application. The matte properties of such compositions can be enhanced, if desired, by addition of one or more mattifying agents. Alternatively, such compositions can be provided with shine or gloss properties by addition of one or more shine or gloss enhancing agents having high refractive index properties.

In accordance with the present invention, the multilayer structure comprises Layer A and Layer B. In certain instances, depending on factors such as ingredient ratios, ingredient concentrations, solvent evaporation characteristics, and Tg of polymers, the layers might be intermixed slightly with each other after application to a lip, resulting in Layer A having a larger amount of A and a smaller amount of B greater and/or Layer B having a larger amount of B and a smaller amount of A. Preferably, Layer A comprises 40% or less of Layer B, preferably 30% or less of Layer B, preferably 20% or less of Layer B, preferably 10% or less of Layer B, and preferably 5% or less of Layer B, including all ranges and subranges therebetween. Similarly, preferably, Layer B comprises 40% or less of Layer A, preferably 30% or less of Layer A, preferably 20% or less of Layer A, preferably 10% or less of Layer B, and preferably 5% or less of Layer A, including all ranges and subranges therebetween. Factors affecting the separation of Component A and Component B after application to a lip can include, for example, those properties discussed above including but not limited to the surface energy of the substrate, the density of each Component, the evaporation properties of the solvent(s), the Tg of the film formers, and/or the viscosity of the film formers.

Although not wishing to be bound by any particular theory, it is believed that Component A should have surface energy properties closer to the surface energy properties of the lip to which it is applied than Component B. For example, the surface energy of skin is estimated to be 36 mN/m. Accordingly, where Component A has a surface energy of about 36 mN/m, it is believed that Component A should migrate to the skin. Component B would preferably have a lower surface energy, making it more likely that it would migrate toward the air interface.

Although not wishing to be bound by any particular theory, it is believed that interfacial tension of Components A and B affects phase separation (in particular, the rate at which the Components A and B separate after application). It is believed that such phase separation can be affected by differences such as those discussed above such as, for example, differences in temperature of the Components A and B, in the Tg of the Components A and B (the higher the Tg of a component, the longer it will take for phase separation), in the weight fraction of the film formers, and/or in the pressure of the Components A and B.

Such differences will also be discussed further below.

Glass Transition Temperature (Tg)

According to preferred embodiments, Component A and/or Component B comprises at least one film forming agent having at least one glass transition temperature lower than 60° C., preferably lower than 55° C., preferably lower than 50° C., and preferably lower than normal human body temperature (98.6° F. or 37° C.). Preferably, Component A and/or Component B comprises at least one film forming agent which has all of its glass transition temperature(s) below human body temperature (98.6° F. or 37° C.). A plasticizer can be added to adjust Tg of the film forming agent(s) as is known in the art. According to preferred embodiments, Layer A and Layer B both comprise at least one forming agent having a glass transition temperature of less than 37° C.

A preferred method of determining Tg is to remove all volatile solvent from the Layer, and determining Tg by Differential Scanning Calorimetry.

Density

According to preferred embodiments, Component A and Component B have different density properties, and the difference is such that Component A and Component B are immiscible in the compositions of the present invention. Preferably, Component A/Layer A and Component B/Layer B have a density difference of 0.001-1 kg/m³, preferably 0.005-0.8 kg/m³, and preferably 0.01-0.6 kg/m³.

Temperature

According to preferred embodiments, Component A and Component B are affected by temperature, and the effect is such that Component A and Component B are immiscible in the compositions of the present invention at temperatures below 50° C. for a predetermined amount of time as is known in the art unlike emulsions which are considered to be stable under such conditions.

Weight Fraction

According to preferred embodiments, Component A and/or Component B comprises at least one polymer such as, for example a film forming agent having a critical molecular weight of entanglement (M_(c)) such that:

If present in Component A, the at least one polymer has an Mc<wMw, where w=weight fraction and Mw=molecular weight of the polymer; and

If present in Component B, the at least one polymer has Mcs≦wMw≦108 g/mol.

Further, according to preferred embodiments, the viscosity of the at least one polymer in Component B is greater than 350 cSt, preferably greater than 500 cSt, preferably greater than 750 cSt, and preferably greater than 1000 cSt, including all ranges and subranges therebetween.

Ingredients

Component A and Component B can differ in various ways based primarily on the different functionalities associated with Layer A and Layer B. For example, where Layer A performs a transfer-resistance or adherence function, ingredients of Component A can be chosen to effect transfer-resistance or adherence. Similarly, where Layer A performs a color-enhancing function, at least one coloring agent can be added to Component A. And, for example, where Layer B performs a gloss- or shine-enhancing function and/or and provides a better feel (for example, affords a more comfortable feeling) and/or provides a barrier layer to inhibit color transfer, ingredients of Component B can be chosen to effect gloss, shine, comfort and/or barrier layer properties. However, it should be understood that at the interface of Layer A and Layer B, the interface of Layer A may possess properties more associated with Layer B (for example, shine) while Layer B may possess properties more associated with Layer A (for example, adhesion).

According to preferred embodiments, Component A comprises at least one film forming agent, at least one coloring agent, or both, and Layer A provides adhesion, transfer-resistance and/or color properties to the multilayer structure. According to such embodiments, Component B may comprise at least one shine-enhancing agent, at least one comfort agent and/or at least one barrier agent, and Layer B provides shine, comfort and/or a barrier properties to the multilayer structure.

According to preferred embodiments, the compositions of the present invention contain less than 1% wax and/or less than 1% fluorinated compound.

According to preferred embodiments, the compositions of the present invention contain less than 0.5% wax and/or less than 0.5% fluorinated compound.

According to preferred embodiments, the compositions of the present invention contain no wax and/or no fluorinated compound.

According to preferred embodiments, at least one of the same solvent(s) is used in Component A and Component B. Preferably, of total solvent present in each Component, the majority in each Component is the same.

According to preferred embodiments, the weight ratio of Component A to Component B is from 1:75 to 15:1, preferably from 1:50 to 10:1, and preferably from 1:50 to 1:1, including all ranges and subranges therebetween.

Examples of acceptable ingredients added to Component A and/or Component B are discussed below.

Film Forming Agent (Film Former)

According to preferred embodiments, Component A comprises at least one film forming agent having at least one glass transition temperature which is lower than normal human body temperature (98.6° F.). Preferably, the at least one film forming agent has all of its glass transition temperature(s) below normal human body temperature (98.6° F.). The Tg property of the at least one film forming agent can result from various ways known in the art such as, for example, the Tg of the film forming agent itself, the combination of different film forming agents to achieve a Tg lower than normal human body temperature, or the combination of film forming agent(s) and plasticizer(s) to achieve a Tg lower than normal human body temperature.

Examples of acceptable classes of film forming agents include acrylic polymers, silicone resins, silicone acrylate copolymers, vinyl pyrrolidone (VP) containing homopolymers and copolymers, polyurethanes, polyolefins and mixtures thereof.

Preferably, the film forming agent(s) is/are selected from the group consisting of silicone resins, silicone acrylate copolymers, acrylate copolymers and mixtures thereof.

Silicone Resin

As used herein, the term “resin” means a crosslinked or non-crosslinked three-dimensional structure. Silicone resin nomenclature is known in the art as “MDTQ” nomenclature, whereby a silicone resin is described according to the various monomeric siloxane units which make up the polymer.

Each letter of “MDTQ” denotes a different type of unit. The letter M denotes the monofunctional unit (CH3)3SiO1/2. This unit is considered to be monofunctional because the silicone atom only shares on oxygen when the unit is part of a polymer. The “M” unit can be represented by the following structure:

At least one of the methyl groups of the M unit may be replaced by another group, e.g., to give a unit with formula [R(CH3)2]SiO1/2, as represented in the following structure:

wherein R is chosen from groups other than methyl groups. Non-limiting examples of such groups other than methyl groups include alkyl groups other than methyl groups, alkene groups, alkyne groups, hydroxyl groups, thiol groups, ester groups, acid groups, ether groups, wherein the groups other than methyl groups may be further substituted.

The symbol D denotes the difunctional unit (CH3)2SiO2/2 wherein two oxygen atoms bonded to the silicone atom are used for binding to the rest of the polymer. The “D” unit, which is the major building block of dimethicone oils, can be represented as:

At least one of the methyl groups of the D unit may be replaced by another group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2).

The symbol T denotes the trifunctional unit, (CH₃)SiO_(3/2) and can be represented as:

At least one of the methyl groups of the T unit may be replaced by another group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2).

Finally, the letter Q means a tetrafunctional unit SiO_(4/2) in which the silicon atom is bonded to four hydrogen atoms, which are themselves bonded to the rest of the polymer.

Thus, a vast number of different silicone polymers can be manufactured. Further, it would be clear to one skilled in the art that the properties of each of the potential silicone polymers will vary depending on the type(s) of monomer(s), the type(s) of substitution(s), the size of the polymeric chain, the degree of cross linking, and size of any side chain(s).

Non-limiting examples of silicone polymers include siloxysilicates and silsesquioxanes.

A non-limiting example of a siloxysilicate is trimethylsiloxysilicate, which may be represented by the following formula:

[(CH₃)₃XSiXO]_(x)X(SiO_(4/2))_(y)

(i.e, MQ units) wherein x and y may, for example, range from 50 to 80. Silsesquioxanes, on the other hand, may be represented by the following formula:

(CH₃SiO_(3/2))_(.x)

(i.e., T Units) wherein x may, for example, have a value of up to several thousand.

Resin MQ, which is available from Wacker, General Electric and Dow Corning, is an example of an acceptable commercially-available siloxysilicate. For example, trimethylsiloxysilicate (TMS) is commercially available from General Electric under the tradename SR1000 and from Wacker under the tradename TMS 803. TMS is also commercially available from Dow Chemical in a solvent, such as for example, cyclomethicone. However, according to the present invention, TMS may be used in the form of 100% active material, that is, not in a solvent.

Suitable silicon resins comprising at least one T unit in accordance with the present invention are disclosed, for example, in U.S. patent applications 2007/0166271, 2011/0038820, 2011/0002869, and 2009/0214458, the entire contents of which are hereby incorporated by reference in their entirety.

Where the silicone resin contains at least one T unit, it may thus be, for example, a T, MT, MTQ or MDTQ resin.

According to preferred embodiments, the unit composition of the silicone resin can be at least 50% T units, or at least 70% T units, or at least 80% T units, or at least 90% T units.

In the M, D and T units listed as examples above, at least one of the methyl groups may be substituted. According to preferred embodiments, the at least one silicone resin comprising at least one trifunctional unit of formula (R)SiO_(3/2) is chosen from the silsesquioxanes of formula: ((R′)SiO_(3/2))_(x), in which x ranges from 100 to 500 and R′ is chosen, independently by trifunctional unit, from a hydrocarbon-based group containing from 1 to 10 carbon atoms or a hydroxyl group, on the condition that at least one R′ is a hydrocarbon-based group. According to preferred embodiments, the hydrocarbon-based group containing from 1 to 10 carbon atoms is a methyl group. According to preferred embodiments, the at least one silicone resin comprising at least one trifunctional unit of formula (R)SiO_(3/2) is chosen from the silsesquioxanes of the formula: ((R′)SiO_(3/2))_(x), in which x ranges from 100 to 500 and R′ is chosen, independently by unit, from CH₃, a hydrocarbon-based group containing from 2 to 10 carbon atoms, or a hydroxyl group, on the condition that at least one R′ is a hydrocarbon-based group.

According to preferred embodiments, the T resins may contain M, D and Q units such that at least 80 mol % or at least 90 mol %, relative to the total amount of silicones, are T units. The T resins may also contain hydroxyl and/or alkoxy groups. The T resins may have a total weight of hydroxyl functions ranging from 2% to 10% and a total weight of alkoxy functions that may be up to 20%; in some embodiments, the total weight of hydroxyl functions ranges from 4% to 8% and the total weight of alkoxy functions may be up to 10%.

The silicone resin may be chosen from silsesquioxanes that are represented by the following formula: ((CH₃)SiO_(3/2))_(x), in which x may be up to several thousand and the CH₃ group may be replaced with an R group, as described previously in the definition of the T units. The number x of T units of the silsesquioxane may be less than or equal to 500, or it may range from 50 to 500, including all ranges and subranges therebetween. The molecular weight of the silicone resin may range from 500 to 50,000 g/mol, from 500 to 20,000 g/mol, or from 500 to 10,000 g/mol, including all ranges and subranges therebetween.

As suitable examples of these silicone resins containing at least one T unit, mention may be made of:

It is thought that the polymer is in a “cage” and “ladder” configuration as represented in the figures below. The average molecular weight of the units in “cage” configuration has been calculated as 536 g/mol. The majority of the polymer is in the “ladder” configuration with ethoxy groups at the ends.

In particular, suitable gelling agents for the oil phase include, but are not limited to, lipophilic or hydrophilic clays.

The term “hydrophilic clay” means a clay that is capable of swelling in water; this clay swells in water and forms after hydration a colloidal dispersion. These clays are products that are already well known per se, which are described, for example, in the book “Mineralogie des argiles”, S. Caillere, S. Henin, M. Rautureau, 2nd edition 1982, Masson, the teaching of which is included herein by way of reference. Clays are silicates containing a cation that may be chosen from calcium, magnesium, aluminium, sodium, potassium and lithium cations, and mixtures thereof. Examples of such products that may be mentioned include clays of the smectite family such as montmorillonites, hectorites, bentonites, beidellites and saponites, and also of the family of vermiculites, stevensite and chlorites. These clays may be of natural or synthetic origin.

Hydrophilic clays that may be mentioned include smectite products such as saponites, hectorites, montmorillonites, bentonites and beidellite. Hydrophilic clays that may be mentioned include synthetic hectorites (also known as laponites), for instance the products sold by the company Laporte under the names Laponite XLG, Laponite RD and Laponite RDS (these products are sodium magnesium silicates and in particular sodium lithium magnesium silicates); bentonites, for instance the product sold under the name Bentone HC by the company Rheox; magnesium aluminium silicates, especially hydrated, for instance the products sold by the Vanderbilt Company under the names Veegum Ultra, Veegum HS and Veegum DGT, or calcium silicates, and especially the product in synthetic form sold by the company under the name Micro-cel C.

The term “lipophilic day” means a clay that is capable of swelling in a lipophilic medium; this clay swells in the medium and thus forms a colloidal dispersion. Examples of lipophilic clays that may be mentioned include modified clays such as modified magnesium silicate (Bentone Gel VS38 from Rheox), and hectorites modified with a C10 to C22 fatty-acid ammonium chloride, for instance hectorite modified with distearyldimethylammonium chloride (CTFA name: disteardimonium hectorite) sold under the name Bentone 38 CE by the company Rheox or Bentone 38V® by the company Elementis.

In particular, among the gelling agents that may be used, mention may be made of silica particles. Preferably, the silica particles are fumed silica particles.

It is in fact possible to modify the surface of silica chemically, by a chemical reaction producing a decrease in the number of silanol groups present on the surface of the silica. The silanol groups can notably be replaced with hydrophobic groups: a hydrophobic silica is then obtained. The hydrophobic groups can be:

trimethylsiloxyl groups, which are notably obtained by treatment of pyrogenic silica in the presence of hexamethyldisilazane. Silicas treated in this way are called “Silica silylate” according to the CTFA (6th edition, 1995). They are for example marketed under the references “AEROSIL R812®” by the company Degussa, “CAB-O-SIL TS-530®” by the company Cabot;

dimethylsilyloxyl or polydimethylsiloxane groups, which are notably obtained by treatment of pyrogenic silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas treated in this way are called “Silica dimethyl silylate” according to the CTFA (6th edition, 1995). They are for example marketed under the references “AEROSIL R972®”, “AEROSIL R974®” by the company Degussa, “CAB-O-SIL TS-610®”, “CAB-O-SIL TS-720®” by the company Cabot.

Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective measurements. The following examples are intended to illustrate the invention without limiting the scope as a result. The percentages are given on a weight basis.

Example 1—Lip Oil Composition Preparation

Lip oil examples were prepared using a high speed mixer. To a high speed mixer cup, all polymers were added. The sample was mixed at 2500-3500 RPM until homogenous. The samples typically were opaque and not clear, and homogeneity was deciphered by the sample smoothness. To the freshly mixed sample, pigments, pigments dispersions, and any other particles were added in addition to the QS solvent. The sample was additionally mixed at 2500-3500 RPM until homogenous.

Example 2—Testing Protocols

Gloss Testing Samples were evaluated for their gloss value using a gloss meter. Sample films were prepared by using a 3 mil wet drawdown bar to deposit a film onto BYK Opacity Chart (#2812). Films were allowed to dry for a minimum of 1 hour and then were evaluated for their gloss values using a BYK Micro-TRI-Gloss meter. From the values captured, the 60 degree value was reported. A value of less than 10 GU was considered to be low gloss; a value of 10-69 GU was considered to be medium gloss; and a value of 70 GU or greater was considered to be high gloss.

Transfer-Resistance: Kiss Test

Samples were tested for their resistance to transfer. The samples were respectively applied by a subject and allowed to dry for 15 minutes. Following the 15 minute dry time, each subject kissed their clean back hand and an image was captured to assess level of transfer. For full transfer, a score was given of 3, while somewhat transfer was given a score of 2, and little to no transfer was given a score of 1.

Self-Leveling Testing

Samples were evaluated for their dried film properties. Samples were casted onto a BYK Opacity Chart (#2812) using a 3 mil wet drawdown bar at room temperature. Samples were allowed to dry for a minimum of 5 hours. After drying, samples were visually and manually evaluated for phase separation and self-leveling properties. In order to assess the phase separation, films were agitated with a gloved finger with force of 35-55 grams of force. In order to insure the same force was applied for all samples, the contrast card was placed on an scale, a weight it places to hold down the film and the scale is tarred. Then a gloved index finger was used to pass across the sample. The pressure applied was sustained within 35-55 g of force. If samples could be roughened it was documented and they were further assessed for recovery of the film by self-leveling. Samples were allowed to rest for a minimum of a 24 hour period and then visually reassessed for interface quality and if there was any level of recovery. Images were also captured of the samples prior to roughening, at initial roughening, and at 24 hours after roughening. After the 24 hour period, it was documented if the sample showed signs of recovery or not.

Bulk Phase Separation

All samples were visually assessed for homogeneity, phase separation, and any additional visual attributes. These evaluations were conducted after the bulk formula was allowed to rest at room temperature for a minimum of 1 hour-72 hours after mixing or agitation.

Example 3—Inventive and Comparative Compositions

The compositions in the following table were prepared and tested according to protocols set forth above. As can be seen, Inventive examples 3 and 5 had improved transfer resistance relative to the market comparative example, as well as a high gloss value. In addition the samples phase separated in bulk, and the inherent self-leveling property was also seen within this samples.
